CROSS-REFERENCE TO RELATED APPLICATION

This application claims the benefit of U.S. Provisional Application No. 60/140,876, filed Jun. 24, 1999.

FIELD OF THE INVENTION

The invention relates to the genetic manipulation of plants, particularly to transforming plants with genes that enhance disease resistance, and breeding program for screening tolerance/resistance lines.

BACKGROUND OF THE INVENTION

Disease in plants is caused by biotic and abiotic causes. Biotic causes include fungi, viruses, bacteria, and nematodes. Of these, fungi are the most frequent causative agent of disease on plants. Abiotic causes of disease in plants include extremes of temperature, water, oxygen, soil pH, plus nutrient-element deficiencies and imbalances, excess heavy metals, and air pollution.

A host of cellular processes enables plants to defend themselves from disease caused by pathogenic agents. These processes apparently form an integrated set of resistance mechanisms that is activated by initial infection and then limits further spread of the invading pathogenic microorganism.

Subsequent to recognition of a potentially pathogenic microbe, plants can activate an array of biochemical responses. Generally, the plant responds by inducing several local responses in the cells immediately surrounding the infection site. The most common resistance response observed in both non-host and race-specific interactions is termed the “hypersensitive response” (HR). In the hypersensitive response, cells contacted by the pathogen, and often neighboring cells, rapidly collapse and dry in a necrotic fleck. Other responses include the deposition of callose, the physical thickening of cell walls by lignification, and the synthesis of various antibiotic small molecules and proteins. Genetic factors in both the host and the pathogen determine the specificity of these local responses, which can be very effective in limiting the spread of infection.

The hypersensitive response in many plant-pathogen interactions results from the expression of a resistance (R) gene in the plant and a corresponding avirulence (avr) gene in the pathogen. (Flor (1971) Ann. Rev. Phytopath. 9:274). This interaction is associated with the rapid, localized cell death of the hypersensitive response. R genes that respond to specific bacterial, fungal, or viral pathogens, have been isolated from a variety of plant species and several appear to encode cytoplasmic proteins.

The resistance gene in the plant and the avirulence gene in the pathogen often conform to a gene-for-gene relationship. That is, resistance to a pathogen is only observed when the pathogen carries a specific avirulence gene and the plant carries a corresponding or complementing resistance gene. The theory has been developed by genetic studies of plant/pathogen interactions in a variety of plant systems (Keen (1990) Ann. Rev. Genet. 24:447-463). Because avrR gene-for-gene relationships are observed in many plant-pathogen systems and are accompanied by a characteristic set of defense responses, a common molecular mechanism underlying avrR gene mediated resistance has been postulated. A simple model which has been proposed is that pathogen avr genes directly or indirectly generate a specific molecular signal (ligand) that is recognized by cognate receptors encoded by plant R genes.

Both plant resistance genes and corresponding pathogen avirulence genes have been cloned. The plant kingdom contains thousands of R genes with specific specificities for viral, bacterial, fungal, or nematode pathogens. Although there are differences in the defense responses induced during different plant-pathogen interactions, some common themes are apparent among R gene-mediated defenses. The function of a given R gene is dependent on the genotype of the pathogen. Plant pathogens produce a diversity of potential signals, and in a fashion analogous to the production of antigens by mammalian pathogens, some of these signals are detectable by some plants.

Recently a number of R genes have been isolated from various plant species that interact with different pathogens (avr) genes (Bent (1996) Plant Cell 8:1757-1771; Hammond-Kosack et al. (1997) Ann. Rev. Plant Physiol. Plant Mol. Biol. 48:575-607; Ellis etal. (1988) Cur. Opin. in Plant Path. 1:288-293). The recent development of new methods for gene isolation in plants has permitted isolation of many R genes from other plant species (Yu et al. (1996) Proc. Natl. Acad. Sci. USA 93:11751-11756; Leister et al. (1998) Proc. Natl. Acad. Sci. USA. 95:370-375). Although the products of most avirulence genes show very little homology with each other, the reported R genes have conserved functional domains such as the protein kinase (PK) domain, leucine-rich regions (LRR), nucleotide-binding sites (NBS) Bent (1996) Plant Cell 8:1757-1771; Ellis et al. (1988) Cur. Opin. in Plant Path. 1:288-293).

The R genes can be classified into four main classes based on the structure of R gene products (Bent (1996) Plant Cell 8:1757-1771; Ellis et al. (1988) Cur. Opin. in Plant Path. 1:288-293; Hammond-Kosack et al. (1997) Ann. Rev. Plant Physiol. Plant Mol. Biol. 48:575-607; NBS-LRR (nucleotide-binding site-Leucine-rich repeat), LRR-TM-PK (Leucine-rich repeat-transmembrane domain-protein kinase), LRR-TM (Leucine-rich repeat-transmembrane domain), and PK (protein kinase). The largest number of characterized R proteins is the NBS-LRR type. These group genes can be recognized into two subgroups by the presence or absence of an amino-terminal region (TIR domain). TIR domain has sequence and structural similarity to the cytoplasmic signaling domains of Toll and interleukin-1 receptor (Baker et al. (1997) Science 276:726-733; Parker et al. (1997) Plant Cell 9:879-894).

The first subgroup includes tobacco TMV N gene, Hammond-Kosack et al. (1997) Ann. Rev. Plant Physiol. Plant Mol. Biol. 48:575-607, L6 (flax rust resistance), Hammond-Kosack et al. (1997) Ann. Rev. Plant Physiol. Plant Mol. Biol. 48:575-607, and RPP5 (downy mildew resistance), Parker et al. (1997) Plant Cell 9:879-894. The second subgroup without TIR domain includes RPS2, RPM1 Hammond-Kosack et al. (1997) Ann. Rev. Plant Physiol. Plant Mol. Biol. 48:575-607, and Prf Salmeron et al. (1996) Cell 86:123-133. These three R genes contain an amino-terminal leucine zipper (LZ) domain. The LZ domain may involve in protein-protein interaction in the signaling pathways. The proteins in these two subclasses signal through different pathways. Proteins in the TIR class signal via a pathway that includes EDS1 (Parker et al. (1996) Plant Cell 8:2033-2046) whereas the other class signals through a pathway that includes NDR1 gene (Centry et al. (1997) Science 278:1963-1965). The function of NBS may relate to HR and evidence has shown that NBS of RPS2 binds nucleotide (Ellis et al. (1988) Curr. Opin. in Plant Path. 1:288-293). Many NBS-LRR plant genes have been identified through plant genome sequencing projects (Botella et al. (1997) Plant J. 12:1197-1121), and by PCR using degenerate primers based on the NBS motifs. Yu et al. (1996) Proc. Natl. Acad Sci. USA 93:11751-11756; Leister et al. (1998) Proc. Natl. Acad. Sci. USA. 95:370-375.

Both LRR-TM-PK and PK classes of R genes contain kinase domain. Ligand binding activates the protein kinase domain. The first receptor-like protein kinase (RLK) gene is maize ZmPK1 that was isolated using degenerate primers to the kinase domain (Walker et al. (1990) Nature 345:743-746). Since then, a number of RLKs have been isolated from plants. The plant RLKs belongs to serine/threonine kinase family except ZmPK1. All of the plant RLKs can be classified according to the features of the predicted extracellular domain and transmambrane domain, such as LRR and TM. The function of kinase in defense signaling pathways has been dissected in the Pto/AvrPto interactions (Oldroyd et al. (1988) Proc. Natl. Acad. Sci. USA 95:10300-10305; Martin et al. (1996) Molecular Aspects of Pathogenicity and Resistance: Requirement for Signal Transduction, (pages 163-186). In the signal transduction, Pto, together with Prf, is required for the hypersensitive response induction after AvrPto perception. Pto also interacts with a family of transcriptional factors-Pti4, Pti5, and Pti6- that binds to a conserved cis-element present in promoter region of many genes encoding PR proteins (Zhou et al. (1997) EMBO J. 16:3207-3218). Expression of PR proteins is specifically enhanced upon Pto-Avrpto recognition in transgenic tobacco proteins (Zhou et al. (1997) EMBO J. 16:3207-3218).

In general, an R gene provides resistance against only some strains of a particular pathogen species. However, it has been demonstrated that R genes can be functional in heterologous systems (Thilmony et al. (1995) Plant Cell 7:1529-1536; Parker et al. (1996) Plant Cell 8:2033-2046). Furthermore, overexpression of R gene Prf activates pathways in a pathogen-independent manner and leads to the activation of systemic acquired resistance (SAR). The transgene-induced SAR has implications for the generation of broad-spectrum disease resistance in agricultural crop plants (Oldroyd et al. (1988) Proc. Natl. Acad. Sci. USA 95:10300-10305). One example of a strain-nonspecific resistance gene, mlo, has been cloned (Buschges et al. (1997) Cell 88:695-705).

As noted, among the causative agents of infectious disease of crop plants, the phytopathogenic fungi play the dominant role. Phytopathogenic fungi cause devastating epidemics, as well as causing significant annual crop yield losses. All of the approximately 300,000 species of flowering plants are attacked by pathogenic fungi. However, a single plant species can be host to only a few fungal species, and similarly, most fungi usually have a limited host range.

Plant disease outbreaks have resulted in catastrophic crop failures that have triggered famines and caused major social change. Generally, the best strategy for plant disease control is to use resistant cultivars selected or developed by plant breeders for this purpose. However, the potential for serious crop disease epidemics persists today, as evidenced by outbreaks of the Victoria blight of oats and southern corn leaf blight. Accordingly, molecular methods are needed to supplement traditional breeding methods to protect plants from pathogen attack.

DETAILED DESCRIPTION OF THE INVENTION

The invention is drawn to methods for creating or enhancing resistance in a plant to plant pests. Accordingly, the methods are also useful in protecting plants against fungal pathogens, viruses, nematodes, insects and the like.

The R genes of the invention can be used as markers in genetic mapping as well as in assessing disease resistance in a plant of interest. Thus, the sequences can be used in breeding programs. See, for example, Gentzbittel et al. (1998) Theor. Appl. Genet. 96:519-523.

Additional uses for the sequences of the invention include using the sequences as bait to isolate other signaling components on defense/resistance pathways and to isolate the corresponding promoter sequences. The sequences may also be used to modulate plant development processes, such as pollen development, regulation of organ shape, differentiation of aleurone and shoot epidermis, embryogenic competence, and cell/cell interactions. See, generally, Sambrook et al. (1989) Molecular Cloning: A Laboratory Manual (2nd ed., Cold Spring Harbor Laboratory Press, Plainview, N.Y.).

Methods for creating or enhancing disease resistance in a plant are provided. The methods involve stably transforming a plant with a DNA construct comprising an sunflower R nucleotide sequence of the invention operably linked to promoter that drives expression in a plant. Such methods find use in agriculture particularly in limiting the impact of plant pathogens on crop plants. The sunflower R nucleotide sequences are selected from nucleotide sequences encoding sunflower R proteins. Preferably, such sunflower R proteins encode protein kinases (PK) and nucleotide binding site-leucine rich repeat-type proteins (NBS-LRR). More preferably, such sunflower R proteins are selected from the proteins whose amino acid sequences are set forth in SEQ ID NOs: 2, 4, and 8 and the proteins encoded by the nucleotide sequences set forth in SEQ ID NOs: 1, 3, 5, 6, 7, 10-13, and 14. While the choice of promoter will depend on the desired timing and location of expression of the antipathogenic nucleotides sequences, specific promoters include pathogen-inducible promoters.

By “disease resistance” is intended that the plants avoid or suppress the disease symptoms that are the outcome of plant-pathogen interaction. That is, pathogens are prevented from causing plant diseases and the associated disease symptoms. The methods of the invention can be utilized to protect plants from disease, particularly those diseases that are caused by plant pathogens, such as broomrape, sclerotina, downey mildew, etc.

The resistance gene (R) analogs of the invention share homology to disease resistance genes from other plants, including TMV resistance gene N, rust resistance Gene M, downy mildew resistance gene, receptor-like protein kinase, and protein kinase. The R genes of the invention have conserved functional domains such as the protein kinase (PK) domain, leucine-rich regions (LRR), nucleotide-binding sites (NBS). Thus, the genes find use in engineering plants for broad-spectrum disease resistance.

Compositions of the invention comprise sunflower R nucleotides. By “sunflower R nucleotides,” is intended coding and antisense sequences for sunflower resistance genes as well as fragments and variants thereof. Nucleotide sequences encoding sunflower resistance proteins are provided in SEQ ID NOs: 1, 3, 5, 6, 7, 10-13, and 14. Alignment of the sequences with other protein kinases are provided in FIGS. 1 and 2. Four sequences having a protein kinase domain are provided; PK1A (SEQ ID NO: 1), PK1B (SEQ ID NO: 3), PK4 (SEQ ID NO: 5) and PK5 (SEQ ID NO: 6). Amino acid sequences for PK1A and PK1B are also provided (SEQ ID NOs: 2 and 4). Six NBS-LRR type analog sequences RS6-8, RAS4-5, RS7-4, RAS5-1, RS6-8 and RS7-4 are provided in SEQ ID NOs: 7, 9-12, and 14, respectively.

Protein kinases play critical roles in regulating of biochemical changes associated with cellular growth. Thus, the sequences of the invention may find use in modulating (decreasing or increasing cellular growth and/or metabolism. The proteins of the invention may be useful for modulating phosphorylation states of molecules.

Compositions of the invention include isolated nucleic acid molecules comprising nucleotide sequences encoding the DNA sequence shown in the sequence listings, or the nucleotide sequence encoding the DNA sequence deposited in a bacteria host, that are involved in modulating cellular growth and/or metabolism. In particular, the present invention provides for isolated nucleic acid molecules comprising nucleotide sequences encoding the amino acid sequences shown in the sequence listing, or the nucleotide sequences encoding the DNA sequences deposited in a bacterial host as Patent Deposit Nos. PTA-139, PTA-140, PTA-141, PTA-142, PTA-135, PTA-137, PTA-136, and PTA-138, and fragments and variants thereof. Further provided are polypeptides having an amino acid sequence encoded by a nucleic acid molecule described herein, for example those set forth in the sequence listings, or those deposited in a bacterial host as Patent Deposit Nos. PTA-139, PTA-140, PTA-141, PTA-142, PTA-135, PTA-137, PTA-136, and PTA-138, and fragments and variants thereof.

Plasmids containing the nucleotide sequences of the invention were deposited with the Patent Depository of the American Type Culture Collection (ATCC), Manassas, Va., on May 26, 2000. The following plasmids were deposited: pHp 15541 containing PK1A, pHp 15542 containing PK1B, pHp 15543 containing PK4, pHp15544 containing PK5, pHp 15537 containing RS6-8, pHp 15539 containing RAS4-5, pHp 15538 containing 7-4, pHp 15540 containing RAS5-1, and assigned Patent Deposit Nos. PTA-139, PTA-140, PTA-141, PTA-142, PTA-135, PTA-137, PTA-136, and PTA-138, respectively. These deposits will be maintained under the terms of the Budapest Treaty on the International Recognition of the Deposit of Microorganisms for the Purposes of Patent Procedure. These deposits were made merely as a convenience for those of skill in the art and are not an admission that a deposit is required under 35 U.S.C. §112.

Thus, the invention encompasses isolated or substantially purified nucleic acid or protein compositions. An “isolated” or “purified” nucleic acid molecule or protein, or biologically active portion thereof, is substantially or essentially free from components that normally accompany or interact with the nucleic acid molecule or protein as found in its naturally occurring environment. Thus, an isolated or purified nucleic acid molecule or protein is substantially free of other cellular material, or culture medium when produced by recombinant techniques, or substantially free of chemical precursors or other chemicals when chemically synthesized. Preferably, an “isolated” nucleic acid is free of sequences (preferably protein encoding sequences) that naturally flank the nucleic acid (i.e., sequences located at the 5′ and 3′ ends of the nucleic acid) in the genomic DNA of the organism from which the nucleic acid is derived. For example, in various embodiments, the isolated nucleic acid molecule can contain less than about 5 kb, 4 kb, 3 kb, 2 kb, 1 kb, 0.5 kb, or 0.1 kb of nucleotide sequences that naturally flank the nucleic acid molecule in genomic DNA of the cell from which the nucleic acid is derived. A protein that is substantially free of cellular material includes preparations of protein having less than about 30%, 20%, 10%, 5%, (by dry weight) of contaminating protein. When the protein of the invention or biologically active portion thereof is recombinantly produced, preferably culture medium represents less than about 30%, 20%, 10%, or 5% (by dry weight) of chemical precursors or non-protein-of-interest chemicals.

Fragments and variants of the disclosed nucleotide sequences and proteins encoded thereby are also encompassed by the present invention. By “fragment” is intended a portion of the nucleotide sequence or a portion of the amino acid sequence and hence protein encoded thereby. Fragments of a nucleotide sequence may encode protein fragments that retain the biological activity of the native protein and hence modulate or regulate gene activity. Alternatively, fragments of a nucleotide sequence that are useful as hybridization probes generally do not encode fragment proteins retaining biological activity. Thus, fragments of a nucleotide sequence may range from at least about 20 nucleotides, about 50 nucleotides, about 100 nucleotides, and up to the full-length nucleotide sequence encoding the proteins of the invention.

A fragment of an R nucleotide sequence that encodes a biologically active portion of an R protein of the invention will encode at least 15, 25, 30, 50, 100, 150, 200, 250, 300, 350, or 400 contiguous amino acids, or up to the total number of amino acids present in a full-length R protein of the invention (for example, 457, 413, 571, or 476 amino acids for SEQ ID NO: 2, 4, 8, or 13, respectively). Fragments of an R nucleotide sequence that are useful as hybridization probes or PCR primers generally need not encode a biologically active portion of an R protein.

Thus, a fragment of an R nucleotide sequence may encode a biologically active portion of an R protein, or it may be a fragment that can be used as a hybridization probe or PCR primer using methods disclosed below. A biologically active portion of an R protein can be prepared by isolating a portion of one of the R nucleotide sequences of the invention, expressing the encoded portion of the R protein (e.g., by recombinant expression in vitro), and assessing the activity of the encoded portion of the R protein. Nucleic acid molecules that are fragments of an R nucleotide sequence comprise at least 16, 20, 50, 75, 100, 150, 200, 250, 300, 350, 400, 450, 500, 550, 600, or 650 nucleotides, or up to the number of nucleotides present in a full-length R nucleotide sequence disclosed herein (for example, 1593, 1559, 2114, 850, 2594, 2793, 670, 1200, 3450, or 1360 nucleotides for SEQ ID NO[s]: 1, 3, 4, 5, 6, 7, 9, 10, 11, 12, or 14, respectively).

By “variants” is intended substantially similar sequences. For nucleotide sequences, conservative variants include those sequences that, because of the degeneracy of the genetic code, encode the amino acid sequence of one of the R polypeptides of the invention. Naturally occurring allelic variants such as these can be identified with the use of well-known molecular biology techniques, as, for example, with polymerase chain reaction (PCR) and hybridization techniques as outlined below. Variant nucleotide sequences also include synthetically derived nucleotide sequences, such as those generated, for example, by using site-directed mutagenesis but which still encode an R protein of the invention. Generally, variants of a particular nucleotide sequence of the invention will have at least 50%, 55%, 60%, 65%, 70%, generally at least 75%, 80%, 85%, preferably about 90% to 95% or more, and more preferably about 98% or more sequence identity to that particular nucleotide sequence as determined by sequence alignment programs described elsewhere herein using default parameters.

By “variant” protein is intended a protein derived from the native protein by deletion (so-called truncation) or addition of one or more amino acids to the N-terminal and/or C-terminal end of the native protein; deletion or addition of one or more amino acids at one or more sites in the native protein; or substitution of one or more amino acids at one or more sites in the native protein. Variant proteins encompassed by the present invention are biologically active, that is they continue to possess the desired biological activity of the native protein, that is, modulating or regulatory activity as described herein. Such variants may result from, for example, genetic polymorphism or from human manipulation. Biologically active variants of a native R protein of the invention will have at least 40%, 50%, 60%, 70%, generally at least 75%, 80%, 85%, preferably about 90% to 95% or more, and more preferably about 98% or more sequence identity to the amino acid sequence for the native protein as determined by sequence alignment programs described elsewhere herein using default parameters. A biologically active variant of a protein of the invention may differ from that protein by as few as 1-15 amino acid residues, as few as 1-10, such as 6-10, as few as 5, as few as 4, 3, 2, or even 1 amino acid residue.

The proteins of the invention may be altered in various ways including amino acid substitutions, deletions, truncations, and insertions. Methods for such manipulations are generally known in the art. For example, amino acid sequence variants of the R proteins can be prepared by mutations in the DNA. Methods for mutagenesis and nucleotide sequence alterations are well known in the art. See, for example, Kunkel (1985) Proc. Natl. Acad. Sci. USA 82:488-492; Kunkel et al. (1987) Methods in Enzymol. 154:367-382; U.S. Pat. No. 4,873,192; Walker and Gaastra, eds. (1983) Techniques in Molecular Biology (MacMillan Publishing Company, New York) and the references cited therein. Guidance as to appropriate amino acid substitutions that do not affect biological activity of the protein of interest may be found in the model of Dayhoff et al. (1978) Atlas of Protein Sequence and Structure (Natl. Biomed. Res. Found., Washington, D.C.), herein incorporated by reference. Conservative substitutions, such as exchanging one amino acid with another having similar properties, may be preferable.

Thus, the genes and nucleotide sequences of the invention include both the naturally occurring sequences as well as mutant forms. Likewise, the proteins of the invention encompass both naturally occurring proteins as well as variations and modified forms thereof. Such variants will continue to possess the desired modulating or regulatory activity. Obviously, the mutations that will be made in the DNA encoding the variant must not place the sequence out of reading frame and preferably will not create complementary regions that could produce secondary mRNA structure. See, EP Patent Application Publication No. 75,444.

The deletions, insertions, and substitutions of the protein sequence encompassed herein are not expected to produce radical changes in the characteristics of the protein. However, when it is difficult to predict the exact effect of the substitution, deletion, or insertion in advance of doing so, one skilled in the art will appreciate that the effect will be evaluated by routine screening assays. That is, the activity can be evaluated by its effect on the plant defense system. See, for example U.S. Pat. No. 5,614,395, herein incorporated by reference.

Variant nucleotide sequences and proteins also encompass sequences and proteins derived from a mutagenic and recombinogenic procedure such as DNA shuffling. With such a procedure, one or more different R coding sequences can be manipulated to create a new R sequence possessing the desired properties. In this manner, libraries of recombinant polynucleotides are generated from a population of related sequence polynucleotides comprising sequence regions that have substantial sequence identity and can be homologously recombined in vitro or in vivo. For example, using this approach, sequence motifs encoding a domain of interest may be shuffled between the R gene of the invention and other known R genes to obtain a new gene coding for a protein with an improved property of interest, such as an increased Km in the case of an enzyme. Strategies for such DNA shuffling are known in the art. See, for example, Stemmer (1994) Proc. Natl. Acad. Sci. USA 91:10747-10751; Stemmer (1994) Nature 370:389-391; Crameri et al. (1997) Nature Biotech. 15:436-438; Moore et al. (1997) J. Mol. Biol. 272:336-347; Zhang et al. (1997) Proc. Natl. Acad. Sci. USA 94:4504-4509; Crameri et al. (1998) Nature 391:288-291; and U.S. Pat. Nos. 5,605,793 and 5,837,458. Alternatively, variants may have been manipulated to lose biological activity. Such variants can be made by site directed mutagenesis and the like.

In this manner, the present invention encompasses the R genes and proteins as well as components and fragments thereof. That is, it is recognized that component polypeptides or fragments of the proteins may be produced which retain activity. These fragments include truncated sequences, as well as N-terminal, C-terminal, internal and internally deleted amino acid sequences of the proteins.

It is recognized that with these nucleotide sequences, antisense constructions, complementary to at least a portion of the messenger RNA (mRNA) for the R genes or a regulatory flanking sequences can be constructed. Antisense nucleotides are constructed to hybridize with the corresponding mRNA. Therefore, modifications of the sequences may be made as long as the sequences hybridize to and interfere with expression of the corresponding mRNA. In this manner, antisense constructions having 70%, preferably 80%, more preferably 85% sequence identity to the corresponding antisense sequences may be used. Furthermore, portions of the antisense nucleotides may be used to disrupt the expression of the target gene. Generally, sequences of at least 50 nucleotides, 100 nucleotides, 200 nucleotides, or greater may be used.

The nucleotide sequences of the invention can be used to isolate corresponding sequences from other organisms, particularly other plants. Methods are readily available in the art for the hybridization of nucleic acid sequences. Coding sequences from other plants may be isolated according to well known techniques based on their sequence homology to the coding sequences set forth herein. In these techniques all or part of the known coding sequence is used as a probe which selectively hybridizes to other R coding sequences present in a population of cloned genomic DNA fragments or cDNA fragments (i.e. genomic or cDNA libraries) from a chosen organism.

In this manner, methods such as PCR, hybridization, and the like can be used to identify such sequences based on their sequence homology to the sequences set forth herein. Sequences isolated based on their sequence identity to the entire R sequence set forth herein or to fragments thereof are encompassed by the present invention. Such sequences include sequences that are orthologs of the disclosed sequences. By “orthologs” is intended genes derived from a common ancestral gene and which are found in different species as a result of speciation. Genes found in different species are considered orthologs when their nucleotide sequences and/or their encoded protein sequences have a high percentage of sequence identity and/or similarity. Functions of orthologs are often highly conserved among species.

In a PCR approach, oligonucleotide primers can be designed for use in PCR reactions to amplify corresponding DNA sequences from cDNA or genomic DNA extracted from any plant of interest. Methods for designing PCR primers and PCR cloning are generally known in the art and are disclosed in Sambrook et al. (1989) Molecular Cloning: A Laboratory Manual (2d ed., Cold Spring Harbor Laboratory Press, Plainview, N.Y.). See also Innis et al., eds.

Known methods of PCR include, but are not limited to, methods using paired primers, nested primers, single specific primers, degenerate primers, gene-specific primers, vector-specific primers, partially-mismatched primers, and the like.

In hybridization techniques, all or part of a known nucleotide sequence is used as a probe that selectively hybridizes to other corresponding nucleotide sequences present in a population of cloned genomic DNA fragments or cDNA fragments (i.e., genomic or cDNA libraries) from a chosen organism. The hybridization probes may be genomic DNA fragments, cDNA fragments, RNA fragments, or other oligonucleotides, and may be labeled with a detectable group such as 32P, or any other detectable marker. Thus, for example, probes for hybridization can be made by labeling synthetic oligonucleotides based on the R sequence of the invention. Methods for preparation of probes for hybridization and for construction of cDNA and genomic libraries are generally known in the art and are disclosed in Sambrook et al. ( 1989) Molecular Cloning: A Laboratory Manual (2d ed., Cold Spring Harbor Laboratory Press, Plainview, N.Y.).

For example, the entire R sequence disclosed herein, or one or more portions thereof, may be used as a probe capable of specifically hybridizing to corresponding R sequences and messenger RNAs. To achieve specific hybridization under a variety of conditions, such probes include sequences that are unique among R sequences and are preferably at least about 10 nucleotides in length, and most preferably at least about 20 nucleotides in length. Such probes may be used to amplify corresponding R sequences from a chosen plant by PCR. This technique may be used to isolate additional coding sequences from a desired plant or as a diagnostic assay to determine the presence of coding sequences in a plant. Hybridization techniques include hybridization screening of plated DNA libraries (either plaques or colonies; see, for example, Sambrook et al. (1989) Molecular Cloning: A Laboratory Manual (2d ed., Cold Spring Harbor Laboratory Press, Plainview, N.Y.).

Hybridization of such sequences may be carried out under stringent conditions. By “stringent conditions” or “stringent hybridization conditions” is intended conditions under which a probe will hybridize to its target sequence to a detectably greater degree than to other sequences (e.g., at least 2-fold over background). Stringent conditions are sequence-dependent and will be different in different circumstances. By controlling the stringency of the hybridization and/or washing conditions, target sequences that are 100% complementary to the probe can be identified (homologous probing). Alternatively, stringency conditions can be adjusted to allow some mismatching in sequences so that lower degrees of similarity are detected (heterologous probing). Generally, a probe is less than about 1000 nucleotides in length, preferably less than 500 nucleotides in length.

Typically, stringent conditions will be those in which the salt concentration is less than about 1.5 M Na ion, typically about 0.01 to 1.0 M Na ion concentration (or other salts) at pH 7.0 to 8.3 and the temperature is at least about 30° C. for short probes (e.g., 10 to 50 nucleotides) and at least about 60° C. for long probes (e.g., greater than 50 nucleotides). Stringent conditions may also be achieved with the addition of destabilizing agents such as formamide. Exemplary low stringency conditions include hybridization with a buffer solution of 30 to 35% formamide, 1 M NaCl, 1% SDS (sodium dodecyl sulphate) at 37° C., and a wash in 1× to 2×SSC (20×SSC=3.0 M NaCl/0.3 M trisodium citrate) at 50 to 55° C. Exemplary moderate stringency conditions include hybridization in 40 to 45% formamide, 1.0 M NaCl, 1% SDS at 37° C., and a wash in 0.5× to 1×SSC at 55 to 60° C. Exemplary high stringency conditions include hybridization in 50% formamide, 1 M NaCl, 1% SDS at 37° C., and a wash in 0.1×SSC at 60 to 65° C. Duration of hybridization is generally less than about 24 hours, usually about 4 to about 12 hours.

Specificity is typically the function of post-hybridization washes, the critical factors being the ionic strength and temperature of the final wash solution. For DNA-DNA hybrids, the Tm can be approximated from the equation of Meinkoth and Wahl (1984) Anal. Biochem. 138:267-284: Tm=81.5° C.+16.6 (log M)+0.41 (%GC)−0.61 (% form)−500/L; where M is the molarity of monovalent cations, %GC is the percentage of guanosine and cytosine nucleotides in the DNA, % form is the percentage of formamide in the hybridization solution, and L is the length of the hybrid in base pairs. The Tm is the temperature (under defined ionic strength and pH) at which 50% of a complementary target sequence hybridizes to a perfectly matched probe. Tm is reduced by about 1° C. for each 1% of mismatching; thus, Tm, hybridization, and/or wash conditions can be adjusted to hybridize to sequences of the desired identity. For example, if sequences with ≧90% identity are sought, the Tm can be decreased 10° C. Generally, stringent conditions are selected to be about 5° C. lower than the thermal melting point (Tm) for the specific sequence and its complement at a defined ionic strength and pH. However, severely stringent conditions can utilize a hybridization and/or wash at 1, 2, 3, or 4° C. lower than the thermal melting point (Tm); moderately stringent conditions can utilize a hybridization and/or wash at 6, 7, 8, 9, or 10° C. lower than the thermal melting point (Tm); low stringency conditions can utilize a hybridization and/or wash at 11, 12, 13, 14, 15, or 20° C. lower than the thermal melting point (Tm). Using the equation, hybridization and wash compositions, and desired Tm, those of ordinary skill will understand that variations in the stringency of hybridization and/or wash solutions are inherently described. If the desired degree of mismatching results in a Tm of less than 45° C. (aqueous solution) or 32° C. (formamide solution), it is preferred to increase the SSC concentration so that a higher temperature can be used. An extensive guide to the hybridization of nucleic acids is found in Tijssen (1993) Laboratory Techniques in Biochemistry and Molecular Biology—Hybridization with Nucleic Acid Probes, Part I, Chapter 2 (Elsevier, N.Y.); and Ausubel et al., eds. (1995) Current Protocols in Molecular Biology, Chapter 2 (Greene Publishing and Wiley-Interscience, New York). See Sambrook et al. (1989) Molecular Cloning: A Laboratory Manual (2d ed., Cold Spring Harbor Laboratory Press, Plainview, N.Y.).

Thus, isolated sequences that encode for an R protein and which hybridize under stringent conditions to the R sequence disclosed herein, or to fragments thereof, are encompassed by the present invention. Such sequences will be at least 50% to 55% homologous, about 60%, 65%, to 70% homologous, and even about 75%, 80%, 85%, 90%, 95% to 98% homologous or more with the disclosed sequence. That is, the sequence identity of sequences may range, sharing at least 50 % to 55%, about 60%, 65% to 70%, and even about 75%, 80%, 85%, 90%, 95% to 98% or more sequence identity.

The following terms are used to describe the sequence relationships between two or more nucleic acids or polynucleotides: (a) “reference sequence”, (b) “comparison window”, (c) “sequence identity”, (d) “percentage of sequence identity”, and (e) “substantial identity”.

(a) As used herein, “reference sequence” is a defined sequence used as a basis for sequence comparison. A reference sequence may be a subset or the entirety of a specified sequence; for example, as a segment of a full-length cDNA or gene sequence, or the complete cDNA or gene sequence.

(b) As used herein, “comparison window” makes reference to a contiguous and specified segment of a polynucleotide sequence, wherein the polynucleotide sequence in the comparison window may comprise additions or deletions (i.e., gaps) compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. Generally, the comparison window is at least 20 contiguous nucleotides in length, and optionally can be 30, 40, 50, 100, or longer. Those of skill in the art understand that to avoid a high similarity to a reference sequence due to inclusion of gaps in the polynucleotide sequence a gap penalty is typically introduced and is subtracted from the number of matches.

Methods of alignment of sequences for comparison are well known in the art. Thus, the determination of percent sequence identity between any two sequences can be accomplished using a mathematical algorithm. Non-limiting examples of such mathematical algorithms are the algorithm of Myers and Miller (1988) CABIOS 4:11-17; the local homology algorithm of Smith et al. (1981) Adv. Appl. Math. 2:482; the homology alignment algorithm of Needleman and Wunsch (1970) J. Mol. Biol. 48:443-453; the search-for-similarity-method of Pearson and Lipman (1988) Proc. Natl. Acad. Sci. 85:2444-2448; the algorithm of Karlin and Altschul (1990) Proc. Natl. Acad. Sci. USA 872264, modified as in Karlin and Altschul (1993) Proc. Natl. Acad. Sci. USA 90:5873-5877.

Computer implementations of these mathematical algorithms can be utilized for comparison of sequences to determine sequence identity. Such implementations include, but are not limited to: CLUSTAL in the PC/Gene program (available from Intelligenetics, Mountain View, Calif.); the ALIGN program (Version 2.0) and GAP, BESTFIT, BLAST, FASTA, and TFASTA in the Wisconsin Genetics Software Package, Version 8 (available from Genetics Computer Group (GCG), 575 Science Drive, Madison, Wis., USA). Alignments using these programs can be performed using the default parameters. The CLUSTAL program is well described by Higgins et al. (1988) Gene 73:237-244 (1988); Higgins et al. (1989) CABIOS 5:151-153; Corpet et al. (1988) Nucleic Acids Res. 16:10881-90; Huang et al. (1992) CABIOS 8:155-65; and Pearson et al. (1994) Meth. Mol. Biol. 24:307-331. The ALIGN program is based on the algorithm of Myers and Miller (1988) supra. A PAM120 weight residue table, a gap length penalty of 12, and a gap penalty of 4 can be used with the ALIGN program when comparing amino acid sequences. The BLAST programs of Altschul et al (1990) J. Mol. Biol. 215:403 are based on the algorithm of Karlin and Altschul (1990) supra. BLAST nucleotide searches can be performed with the BLASTN program, score=100, wordlength=12, to obtain nucleotide sequences homologous to a nucleotide sequence encoding a protein of the invention. BLAST protein searches can be performed with the BLASTX program, score=50, wordlength=3, to obtain amino acid sequences homologous to a protein or polypeptide of the invention. To obtain gapped alignments for comparison purposes, Gapped BLAST (in BLAST 2.0) can be utilized as described in Altschul et al. (1997) Nucleic Acids Res. 25:3389. Alternatively, PSI-BLAST (in BLAST 2.0) can be used to perform an iterated search that detects distant relationships between molecules. See Altschul et al. (1997) supra. When utilizing BLAST, Gapped BLAST, PSI-BLAST, the default parameters of the respective programs (e.g., BLASTN for nucleotide sequences, BLASTX for proteins) can be used. See http://www.ncbi.nlm.nih.gov. Alignment may also be performed manually by inspection.

Unless otherwise stated, sequence identity/similarity values provided herein refer to the value obtained using GAP version 10 using the following parameters: % identity using GAP Weight of 50 and Length Weight of 3; % similarity using Gap Weight of 12 and Length Weight of 4, or any equivalent program. By “equivalent program” is intended any sequence comparison program that, for any two sequences in question, generates an alignment having identical nucleotide or amino acid residue matches and an identical percent sequence identity when compared to the corresponding alignment generated by GAP Version 10.

GAP uses the algorithm of Needleman and Wunsch (1970) J. Mol. Biol. 48: 443-453, to find the alignment of two complete sequences that maximizes the number of matches and minimizes the number of gaps. GAP considers all possible alignments and gap positions and creates the alignment with the largest number of matched bases and the fewest gaps. It allows for the provision of a gap creation penalty and a gap extension penalty in units of matched bases. GAP must make a profit of gap creation penalty number of matches for each gap it inserts. If a gap extension penalty greater than zero is chosen, GAP must, in addition, make a profit for each gap inserted of the length of the gap times the gap extension penalty. Default gap creation penalty values and gap extension penalty values in Version 10 of the Wisconsin Genetics Software Package for protein sequences are 8 and 2, respectively. For nucleotide sequences the default gap creation penalty is 50 while the default gap extension penalty is 3. The gap creation and gap extension penalties can be expressed as an integer selected from the group of integers consisting of from 0 to 200. Thus, for example, the gap creation and gap extension penalties can be 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 15, 20, 25, 30, 35, 40, 45, 50, 55, 60, 65 or greater.

GAP presents one member of the family of best alignments. There may be many members of this family, but no other member has a better quality. GAP displays four figures of merit for alignments: Quality, Ratio, Identity, and Similarity. The Quality is the metric maximized in order to align the sequences. Ratio is the quality divided by the number of bases in the shorter segment. Percent Identity is the percent of the symbols that actually match. Percent similarity is the percent of the symbols that are similar. Symbols that are across from gaps are ignored. A similarity is scored when the scoring matrix value for a pair of symbols is greater than or equal to 0.50, the similarity threshold. The scoring matrix used in Version 10 of the Wisconsin Genetics Software Package is BLOSUM62 (see Henikoff and Henikoff (1989) Proc. Natl. Acad. Sci. USA 89:10915).

(c) As used herein, “sequence identity” or “identity” in the context of two nucleic acid or polypeptide sequences makes reference to the residues in the two sequences that are the same when aligned for maximum correspondence over a specified comparison window. When percentage of sequence identity is used in reference to proteins it is recognized that residue positions which are not identical often differ by conservative amino acid substitutions, where amino acid residues are substituted for other amino acid residues with similar chemical properties (e.g., charge or hydrophobicity) and therefore do not change the functional properties of the molecule. When sequences differ in conservative substitutions, the percent sequence identity may be adjusted upwards to correct for the conservative nature of the substitution. Sequences that differ by such conservative substitutions are said to have “sequence similarity” or “similarity”. Means for making this adjustment are well known to those of skill in the art. Typically this involves scoring a conservative substitution as a partial rather than a full mismatch, thereby increasing the percentage sequence identity. Thus, for example, where an identical amino acid is given a score of 1 and a non-conservative substitution is given a score of zero, a conservative substitution is given a score between zero and 1. The scoring of conservative substitutions is calculated, e.g., as implemented in the program PC/GENE (Intelligenetics, Mountain View, Calif.).

(d) As used herein, “percentage of sequence identity” means the value determined by comparing two optimally aligned sequences over a comparison window, wherein the portion of the polynucleotide sequence in the comparison window may comprise additions or deletions (i.e., gaps) as compared to the reference sequence (which does not comprise additions or deletions) for optimal alignment of the two sequences. The percentage is calculated by determining the number of positions at which the identical nucleic acid base or amino acid residue occurs in both sequences to yield the number of matched positions, dividing the number of matched positions by the total number of positions in the window of comparison, and multiplying the result by 100 to yield the percentage of sequence identity.

(e)(i) The term “substantial identity” of polynucleotide sequences means that a polynucleotide comprises a sequence that has at least 70% sequence identity, preferably at least 80%, more preferably at least 90%, and most preferably at least 95%, compared to a reference sequence using one of the alignment programs described using standard parameters. One of skill in the art will recognize that these values can be appropriately adjusted to determine corresponding identity of proteins encoded by two nucleotide sequences by taking into account codon degeneracy, amino acid similarity, reading frame positioning, and the like. Substantial identity of amino acid sequences for these purposes normally means sequence identity of at least 60%, more preferably at least 70%, 80%, 90%, and most preferably at least 95%.

Another indication that nucleotide sequences are substantially identical is if two molecules hybridize to each other under stringent conditions. Generally, stringent conditions are selected to be about 5° C. lower than the thermal melting point (Tm) for the specific sequence at a defined ionic strength and pH. However, stringent conditions encompass temperatures in the range of about 1° C. to about 20° C. lower than the Tm, depending upon the desired degree of stringency as otherwise qualified herein. Nucleic acids that do not hybridize to each other under stringent conditions are still substantially identical if the polypeptides they encode are substantially identical. This may occur, e.g., when a copy of a nucleic acid is created using the maximum codon degeneracy permitted by the genetic code. One indication that two nucleic acid sequences are substantially identical is when the polypeptide encoded by the first nucleic acid is immunologically cross reactive with the polypeptide encoded by the second nucleic acid.

(e)(ii) The term “substantial identity” in the context of a peptide indicates that a peptide comprises a sequence with at least 70% sequence identity to a reference sequence, preferably 80%, more preferably 85%, most preferably at least 90% or 95% sequence identity to the reference sequence over a specified comparison window. Preferably, optimal alignment is conducted using the homology alignment algorithm of Needleman and Wunsch (1970) J. Mol. Biol. 48:443-453. An indication that two peptide sequences are substantially identical is that one peptide is immunologically reactive with antibodies raised against the second peptide. Thus, a peptide is substantially identical to a second peptide, for example, where the two peptides differ only by a conservative substitution. Peptides that are “substantially similar” share sequences as noted above except that residue positions that are not identical may differ by conservative amino acid changes.

The invention is drawn to compositions and methods for inducing resistance in a plant to plant pests. Accordingly, the compositions and methods are also useful in protecting plants against fungal pathogens, viruses, nematodes, insects and the like.

By “disease resistance” is intended that the plants avoid the disease symptoms that are the outcome of plant-pathogen interactions. That is, pathogens are prevented from causing plant diseases and the associated disease symptoms, or alternatively, the disease symptoms caused by the pathogen is minimized or lessened. The methods of the invention can be utilized to protect plants from disease, particularly those diseases that are caused by plant pathogens.

The R sequences or antisense R sequences of the invention can be introduced into any plant in accordance with the methods disclosed herein to enhance or create resistance to plant pests. The sequences to be introduced may be used in expression cassettes for expression in any plant of interest where expression in the plant cell is necessary for description. In other instances, such as for description or recombination, oligonucleotides are synthesized, purified and introduced into the plant cell.

The R sequences of the invention are provided in expression cassettes for expression in the plant of interest. The cassette will include 5′ and 3′ regulatory sequences operably linked to an R sequence of the invention. By “operably linked” is intended a functional linkage between a promoter and a second sequence, wherein the promoter sequence initiates and mediates transcription of the DNA sequence corresponding to the second sequence. Generally, operably linked means that the nucleic acid sequences being linked are contiguous and, where necessary to join two protein coding regions, contiguous and in the same reading frame. The cassette may additionally contain at least one additional gene to be co-transformed into the organism. Alternatively, the additional gene(s) can be provided on multiple expression cassettes.

Such an expression cassette is provided with a plurality of restriction sites for insertion of the R sequence to be under the transcriptional regulation of the regulatory regions. The expression cassette may additionally contain selectable marker genes.

The expression cassette will include in the 5′-3′ direction of transcription, a transcriptional and translational initiation region, an R sequence of the invention, and a transcriptional and translational termination region functional in plants. The transcriptional initiation region, the promoter, may be native or analogous or foreign or heterologous to the plant host. Additionally, the promoter may be the natural sequence or alternatively a synthetic sequence. By “foreign” is intended that the transcriptional initiation region is not found in the native plant into which the transcriptional initiation region is introduced. As used herein, a chimeric gene comprises a coding sequence operably linked to a transcription initiation region that is heterologous to the coding sequence.

A number of promoters can be used in the practice of the invention. The promoters can be selected based on the desired outcome. For example, constitutive, inducible, particularly pathogen-inducible, or tissue specific promoters may be used. Such promoters include those from pathogenesis-related proteins (PR proteins), which are induced following infection by a pathogen; e.g., PR proteins, SAR proteins, beta-1,3-glucanase, chitinase, etc. See, for example, Redolfi et al. (1983) Neth. J. Plant Pathol. 89:245-254; Uknes et al. (1992) The Plant Cell 4:645-656; and Van Loon (1985) Plant Mol. Virol. 4:111-116.

Of interest are promoters that are expressed locally at or near the site of pathogen infection. See, for example, Marineau et al. (1987) Plant Mol. Biol. 9:335-342; Matton et al. (1989) Molecular Plant-Microbe Interactions 2:325-331; Somsisch et al. (1986) Proc. Natl. Acad. Sci. USA 83:2427-2430; Somsisch et al. (1988) Molecular and General Genetics 2:93-98; and Yang, Y (1996) Proc. Natl. Acad. Sci. USA 93:14972-14977. See also, Chen et al. (1996) Plant J. 10:955-966; Zhang and Sing (1994) Proc. Natl. Acad. Sci. USA 91:2507-2511; Warner et al. (1993) Plant J. 3:191-201; Siebertz et al. (1989) Plant Cell 1:961-968; and the references cited therein. Of particular interest is the inducible promoter for the maize PRms gene, whose expression is induced by the pathogen Fusarium moniliforme (see, for example, Cordero et al. (1992) Physiological and Molecular Plant Pathology 41:189-200).

Constitutive promoters include, for example, the core promoter of the Rsyn7 promoter and other constitutive promoters disclosed in WO 99/43838, the 35S promoter, the core 35S promoter, and the like. Other constitutive promoters include, for example, U.S. Pat. Nos. 5,608,149; 5,608,144; 5,604,121; 5,569,597; 5,466,785; 5,399,680; 5,268,463; 5,608,142. see also, co-pending application entitled “Constitutive Maize Promoters, application Ser. No. 09/257,584 filed Feb. 25, 1999, and herein incorporated by reference.

Tissue specific promoters include those described in Yamamoto et al. (1997) Plant J. 12(2):255-265; Kawamata et al. (1997) Plant Cell Physiol. 38(7):792-803; Hansen et al. (1997) Mol.

(1993) Plant J. 4(3):495-505.

While it may be preferable to express the sequences using heterologous promoters, the native promoter sequences may be used. Such constructs would change expression levels of R protein in the plant or plant cell. Thus, the phenotype of the plant or plant cell is altered.

The termination region may be native with the transcriptional initiation region, may be native with the operably linked DNA sequence of interest, or may be derived from another source. Convenient termination regions are available from the Ti-plasmid of A. tumefaciens, such as the octopine synthase and nopaline synthase termination regions. See also Guerineau et al. (1991) Mol. Gen. Genet. 262:141-144; Proudfoot (1991) Cell 64:671-674; Sanfacon et al. (1991) Genes Dev. 5:141-149; Mogen et al. (1990) Plant Cell 2:1261-1272; Munroe et al. (1990) Gene 91:151-158; Ballas et al. (1989) Nucleic Acids Res. 17:7891-7903; and Joshi et al. (1987) Nucleic Acid Res. 15:9627-9639.

Where appropriate, the gene(s) may be optimized for increased expression in the transformed plant. That is, the genes can be synthesized using plant-preferred codons for improved expression. See, for example, Campbell and Gowri (1990) Plant Physiol. 92:1-11 for a discussion of host-preferred codon usage. Methods are available in the art for synthesizing plant-preferred genes. See, for example, U.S. Pat. Nos. 5,380,831, and 5,436,391, and Murray et al. (1989) Nucleic Acids Res. 17:477-498, herein incorporated by reference.

Additional sequence modifications are known to enhance gene expression in a cellular host. These include elimination of sequences encoding spurious polyadenylation signals, exon-intron splice site signals, transposon-like repeats, and other such well-characterized sequences that may be deleterious to gene expression. The G-C content of the sequence may be adjusted to levels average for a given cellular host, as calculated by reference to known genes expressed in the host cell. When possible, the sequence is modified to avoid predicted hairpin secondary mRNA structures.

The expression cassettes may additionally contain 5′ leader sequences in the expression cassette construct. Such leader sequences can act to enhance translation. Translation leaders are known in the art and include: picornavirus leaders, for example, EMCV leader (Encephalomyocarditis 5′ noncoding region) (Elroy-Stein et al. (1989) Proc. Natl. Acad. Sci. USA 86:6126-6130); potyvirus leaders, for example, TEV leader (Tobacco Etch Virus) (Gallie et al. (1995) Gene 165(2):233-238), MDMV leader (Maize Dwarf Mosaic Virus) (Virology 154:9-20), and human immunoglobulin heavy-chain binding protein (BiP) (Macejak et al. (1991) Nature 353:90-94); untranslated leader from the coat protein mRNA of alfalfa mosaic virus (AMV RNA 4) (Jobling et al. (1987) Nature 325:622-625); tobacco mosaic virus leader (TMV) (Gallie et al. (1989) in Molecular Biology of RNA, ed. Cech (Liss, N.Y.), pp. 237-256); and maize chlorotic mottle virus leader (MCMV) (Lommel et al. (1991) Virology 81:382-385). See also, Della-Cioppa et al. (1987) Plant Physiol. 84:965-968. Other methods known to enhance translation can also be utilized, for example, introns, and the like.

Generally, the expression cassette will comprise a selectable marker gene for the selection of transformed cells. Selectable marker genes are utilized for the selection of transformed cells or tissues. Marker genes include genes encoding antibiotic resistance, such as those encoding neomycin phosphotransferase II (NEO) and hygromycin phosphotransferase (HPT), as well as genes conferring resistance to herbicidal compounds, such as glufosinate ammonium, bromoxynil, imidazolinones, and 2,4-dichlorophenoxyacetate (2,4-D).

The above list of selectable marker genes is not meant to be limiting. Any selectable marker gene can be used in the present invention.

In preparing the expression cassette, the various DNA fragments may be manipulated, so as to provide for the DNA sequences in the proper orientation and, as appropriate, in the proper reading frame. Toward this end, adapters or linkers may be employed to join the DNA fragments or other manipulations may be involved to provide for convenient restriction sites, removal of superfluous DNA, removal of restriction sites, or the like. For this purpose, in vitro mutagenesis, primer repair, restriction, annealing, resubstitutions, e.g., transitions and transversions, may be involved.

The sequences of the present invention can be used to transform or transfect any plant. In this manner, genetically modified plants, plant cells, plant tissue, seed, and the like can be obtained. Transformation protocols as well as protocols for introducing nucleotide sequences into plans may vary depending on the type of plant or plant cell, i.e. monocot or dicot, targeted for transformation. It is recognized that the transformation protocols may be used for transfection or introduction of the oligonucleotide sequences to disrupt R gene function. Suitable methods of introducing nucleotide sequences into plant cells and subsequent insertion into the plant genome include microinjection (Crossway et al. (1986) Biotechniques 4:320-334), electroporation (Riggs et al. (1986) Proc. Natl. Acad Sci. USA 83:5602-5606, Agrobacterium-mediated transformation (Townsend et al., U.S. Pat.

The cells that have been transformed may be grown into plants in accordance with conventional ways. See, for example, McCormick et al. (1986) Plant Cell Reports 5:81-84. These plants may then be grown, and either pollinated with the same transformed strain or different strains, and the resulting hybrid having constitutive expression of the desired phenotypic characteristic identified. Two or more generations may be grown to ensure that expression of the desired phenotypic characteristic is stably maintained and inherited and then seeds harvested to ensure expression of the desired phenotypic characteristic has been achieved.

The present invention may be used for transformation of any plant species, including, but not limited to, monocots and dicots. Examples of plant species of interest include, but are not limited to, corn (Zea mays), Brassica sp. (e.g., B. napus, B. rapa, B. juncea), particularly those Brassica species useful as sources of seed oil, alfalfa (Medicago sativa), rice (Oryza sativa), rye (Secale cereale), sorghum (Sorghum bicolor, Sorghum vulgare), millet (e.g., pearl millet (Pennisetum glaucum), proso millet (Panicum miliaceum), foxtail millet (Setaria italica), finger millet (Eleusine coracana)), sunflower (Helianthus annuus), safflower (Carthamus tinctorius), wheat (Triticum aestivum), soybean (Glycine max), tobacco (Nicotiana tabacum), potato (Solanum tuberosum), peanuts (Arachis hypogaea), cotton (Gossypium barbadense, Gossypium hirsutum), sweet potato (Ipomoea batatus), cassava (Manihot esculenta), coffee (Coffea spp.), coconut (Cocos nucifera), pineapple (Ananas comosus), citrus trees (Citrus spp.), cocoa (Theobroma cacao), tea (Camellia sinensis), banana (Musa spp.), avocado (Persea americana), fig (Ficus casica), guava (Psidium guajava), mango (Mangifera indica), olive (Olea europaea), papaya (Carica papaya), cashew (Anacardium occidentale), macadamia (Macadamia integrifolia), almond (Prunus amygdalus), sugar beets (Beta vulgaris), sugarcane (Saccharum spp.), oats, barley, vegetables, ornamentals, and conifers.

Vegetables include tomatoes (Lycopersicon esculentum), lettuce (e.g., Lactuca sativa), green beans (Phaseolus vulgaris), lima beans (Phaseolus limensis), peas (Lathyrus spp.), and members of the genus Cucumis such as cucumber (C. sativus), cantaloupe (C. cantalupensis), and musk melon (C. melo). Ornamentals include azalea (Rhododendron spp.), hydrangea (Macrophylla hydrangea), hibiscus (Hibiscus rosasanensis), roses (Rosa spp.), tulips (Tulipa spp.), daffodils (Narcissus spp.), petunias (Petunia hybrida), carnation (Dianthus caryophyllus), poinsettia (Euphorbia pulcherrima), and chrysanthemum.

Conifers that may be employed in practicing the present invention include, for example, pines such as loblolly pine (Pinus taeda), slash pine (Pinus elliotii), ponderosa pine (Pinus ponderosa), lodgepole pine (Pinus contorta), and Monterey pine (Pinus radiata); Douglas-fir (Pseudotsuga menziesii); Western hemlock (Tsuga canadensis); Sitka spruce (Picea glauca); redwood (Sequoia sempervirens); true firs such as silver fir (Abies amabilis) and balsam fir (Abies balsamea); and cedars such as Western red cedar (Thuja plicata) and Alaska yellow-cedar (Chamaecyparis nootkatensis). Preferably, plants of the present invention are crop plants (for example, corn, alfalfa, sunflower, Brassica, soybean, cotton, safflower, peanut, sorghum, wheat, millet, tobacco, etc.), more preferably corn and soybean plants, yet more preferably corn plants.

Plants of particular interest include grain plants that provide seeds of interest, oil-seed plants, and leguminous plants. Seeds of interest include grain seeds, such as corn, wheat, barley, rice, sorghum, rye, etc. Oil-seed plants include cotton, soybean, safflower, sunflower, Brassica, maize, alfalfa, palm, coconut, etc. Leguminous plants include beans and peas. Beans include guar, locust bean, fenugreek, soybean, garden beans, cowpea, mungbean, lima bean, fava bean, lentils, chickpea, etc.

The methods of the invention can be used with other methods for increasing pathogen resistance in plants. See, for example, Cai et al. (1997) Science 275:832-834; Roberts and Gallum (1984) J. Heredity 75:147-148; Ryerson and Heath (1996) Plant Cell 8:393-402 and Dangl et al. (1996) Plant Cell 8:1793-1807.

The R sequences of the invention are also useful as molecular markers. Such markers are useful in breeding programs, particularly those aimed at improving disease resistance. The sunflower R sequences have been mapped to chromosome locations and these positions related to known disease resistance loci.

The present invention provides a method of genotyping a plant comprising a polynucleotide of the present invention. Genotyping provides a means of distinguishing homologs of a chromosome pair and can be used to differentiate segregants in a plant population. Molecular marker methods can be used for phylogenetic studies, characterizing genetic relationships among crop varieties, identifying crosses or somatic hybrids, localizing chromosomal segments affecting monogenic traits, map based cloning, and the study of quantitative inheritance. See, e.g., Plant Molecular Biology: A Laboratory Manual, Chapter 7, Clark, Ed., Springer-Verlag, Berlin (1997). For molecular marker methods, see generally, The DNA Revolution by Andrew H. Paterson (1996) (Chapter 2) in: Genome Mapping in Plants (ed. Andrew H. Paterson) by Academic Press/R. G. Landis Company, Austin, Tex., pp. 7-21.

The particular method of genotyping in the present invention may employ any number of molecular marker analytic techniques such as, but not limited to, restriction fragment length polymorphisms (RFLPs). RFLPs are the product of allelic differences between DNA restriction fragments caused by nucleotide sequence variability. As is well known to those of skill in the art, RFLPs are typically detected by extraction of genomic DNA and digestion with a restriction enzyme. Generally, the resulting fragments are separated according to size and hybridized with a probe; single copy probes are preferred. Restriction fragments from homologous chromosomes are revealed. Differences in fragment size among alleles represent an RFLP. Thus, the present invention further provides a means to follow segregation of a gene or nucleic acid of the present invention as well as chromosomal sequences genetically linked to these genes or nucleic acids using such techniques as RFLP analysis. Linked chromosomal sequences are within 50 centiMorgans (cM), often within 40 or 30 cM, preferably within 20 or 10 cM, more preferably within 5, 3, 2, or 1 cM of a gene.

In the present invention, the nucleic acid probes employed for molecular marker mapping of plant nuclear genomes selectively hybridize, under selective hybridization conditions, to a gene encoding a polynucleotide of the present invention. In one embodiment, the probes are selected from polynucleotides of the present invention. Typically, these probes are cDNA probes or PstI genomic clones. The length of the probes is discussed in greater detail, supra, but are typically at least 15 bases in length, more preferably at least 20, 25, 30, 35, 40, or 50 bases in length. Generally, however, the probes are less than about 1 kilobase in length. Preferably, the probes are single copy probes that hybridize to a unique locus in a haploid chromosome complement. Some exemplary restriction enzymes employed in RFLP mapping are EcoRI, EcoRv, and SstI. As used herein the term “restriction enzyme” includes reference to a composition that recognizes and, alone or in conjunction with another composition, cleaves at a specific nucleotide sequence.

The method of detecting an RFLP comprises the steps of (a) digesting genomic DNA of a plant with a restriction enzyme; (b) hybridizing a nucleic acid probe, under selective hybridization conditions, to a sequence of a polynucleotide of the present of said genomic DNA; (c) detecting therefrom a RFLP. Other methods of differentiating polymorphic (allelic) variants of polynucleotides of the present invention can be had by utilizing molecular marker techniques well known to those of skill in the art including such techniques as: 1) single-stranded conformation analysis (SSCP); 2) denaturing gradient gel electrophoresis (DGGE); 3) RNase protection assays; 4) allele-specific oligonucleotides (ASOs); 5) the use of proteins which recognize nucleotide mismatches, such as the E. coli mutS protein; and 6) allele-specific PCR. Other approaches based on the detection of mismatches between the two complementary DNA strands include clamped denaturing gel electrophoresis (CDGE); heteroduplex analysis (HA); and chemical mismatch cleavage (CMC). Exemplary polymorphic variants are provided in Table I, supra. Thus, the present invention further provides a method of genotyping comprising the steps of contacting, under stringent hybridization conditions, a sample suspected of comprising a polynucleotide of the present invention with a nucleic acid prober. Generally, the sample is a plant sample; preferably, a sample suspected of comprising a sunflower polynucleotide of the present invention (e.g., gene, mRNA). The nucleic acid probe selectively hybridizes, under stringent conditions, to a subsequence of a polynucleotide of the present invention comprising a polymorphic marker. Selective hybridization of the nucleic acid probe to the polymorphic marker nucleic acid sequence yields a hybridization complex. Detection of the hybridization complex indicates the presence of that polymorphic marker in the sample. In one embodiment, the nucleic acid probe comprises a polynucleotide of the present invention.

The following examples are offered by way of illustration and not by way of limitation.

EXAMPLE 1

Cloning of Sunflower Disease Resistant Genes

MATERIALS AND METHODS

Plant Material

Sunflower plants and maize plants were grown in the greenhouse. For PCR-based isolation of R gene homologs and pto-like protein kinase genes we used the sunflower line SMF 3. Sunflower pathogen, Scierotinia sclerotiorum was maintained on PDA plate at 20° C. in dark.

PCR Amplification of Sunflower R Gene and Pto Homologs

To isolate R gene homologs, two conserved regions (NBS-LRR) of amino acid identity in the N gene from tobacco, the PRS2 gene from Arabidopsis, and the L6 gene from flax were used to design degenerate oligonucleotide primers as reported previously (Leister et al. (1998) Proct. Natl. Acad. Sci. USA 95:370-375) with the modifications as indicated in Table 1. Degenerate primers were designed based on motifs conserved between pto, fen, and APK1 in order to clone sunflower pto homologs. Table 1 summarizes the degenerate primers used for cloning R homologs and pto-like genes.

PCRs were performed in a total volume of 25 ul in 10 mM Tris-HCL, pH 8.3; 1.5 mM MgCL2; 50 mM KCL; 0.1 mM dNTPs; 0.25 uM of each primer with 0.5 units of advantage cDNA polymerase mix (Clontech) or Pwo DNA ploymerase (Boehringer). Genomic DNA and/or cDNA library mixtures were used as template for PCR amplification.

Amplified PCR fragments with the expected sizes of 450-550 bp for NBS-LRR primers, 340 bp for NBS primers and 600 bp for pto primers were individually sliced out of gels for a second round of PCR amplification with the same conditions as the initial PCR. Each second-round PCR amplification yielded a single band of the expected size which represented a heterogeneous population of PCR products. The PCR products were cloned into a TA vector (Clontech) according to the suppliers instructions. Fifty clones of each PCR product population were picked randomly and grouped by restriction analysis using 4-bp recognition enzymes (Alu I and Msp I). At least one representative clone of each identified group was selected for DNA sequencing using an Applied Biosystems 373A (ABI) automated sequencer at the Nucleic Acid Analysis Facility of Pioneer Hi-Bred International, Incorporated. DNA sequence analysis was carried out with the Sequencer (3.0). Multiple-sequence alignment (Clustal W) of the DNA sequence and phylogenetic analysis (PHYLIP) were made with the Curatool (CuraGen).

Construction of the Sclerotinia-infected and Resistance-enhanced (oxox-induced) Sunflower cDNA Libraries

Six-week-old SMF3 sunflower plants were infected with Sclerotinia sclerotritim by petiole inoculation with Sclerotinia-infested carrot plugs. Six days after infection, leaf and stem tissues were collected from infected plants for total RNA isolation. Total RNA was also isolated from sunflower transgenic plants (SID 610255) expressing a wheat oxalate oxidase gene (oxox) at the six-week stage. Our previous studies have showed that elevated levels of H2O2, SA and PR1 protein were detected in oxox-transgenic plants at the six-week stage and the plants showed more resistance to Sclerotinia infection WO99/04013. mRNA was isolated using an mRNA purification kit (BRL) according to the manufacturer's instructions. cDNA libraries were constructed with the ZAP-cDNA synthesis kit into pBluescript phagemid (Stratagene). A cDNA library mixture for PCR cloning was made of oxox transgenic stem and Sclerotinia-infected leaf libraries (1:2 mix).

Isolation of Full-length or Flanking Sequences by PCR Amplification of cDNA Ends

Full-length or flanking sequences of identified sunflower R gene and PK gene homologues were isolated using directly amplified Sclerotinia-infected cDNA libraries or the Marathon cDNA Amplification Kit (Clontech) according to the manufacturer's instructions. To facilitate cloning full-length cDNAs from the initial cloned regions, we designed a pair of 28 bp vector primers flanking the cloned cDNAs on both the 3′ and 5′ ends of the pBS vector. The vector primers were utilized to directionally amplify either a 5′ or 3′ end of a cDNA using one vector primer (pBS-upper or pBS-lower) and a gene-specific primer. Once the anticipated 5′ end of a specific gene with an intact ATG start codon was cloned and sequenced, the full-length cDNA was amplified using a second gene-specific primer containing sequence upstream of the ATG and a vector primer at the 3′ end. The PCR products were cloned and sequenced as described above.

RESULTS

Clone Full-length of cDNAs Related to Disease Resistance

A PCR-based cloning method to efficiently isolate full-length cDNAs of disease resistance-related R genes and protein kinase genes, as well as other plant defense genes, from sunflower cDNA libraries has been developed. A cDNA library mixture containing both oxox-transgenic cDNA library and Sclerotinia-infected cDNA library (1:2 mix) was used as a source of templates for PCR amplification. Using cDNA libraries as a source of DNA templates for PCR amplification had two benefits: (1) the number of unexpected PCR products was reduced as compared with genomic DNA as a source of templates and (2) disease-induced cDNA libraries increased the chance of isolating defense-related genes. To facilitate cloning full-length cDNAs from the initially cloned regions, a pair of 28 bp vector primers (Table 2) the flanking cDNAs on the ends (3′ and 5′) of pBS vector was designed and used to directionally amplify either the 5′ or 3′ end of the cDNA with one of the vector primers paired with a gene-specific primer (Table 2a and 2b). The 5′ end of the gene with the intact ATG start codon was cloned and sequenced. The full-length cDNA was amplified by using a second gene-specific primer containing the upstream ATG region sequence and a vector primer at the 3′ end. The PCR products were cloned and sequenced as described above. This method was used in the full-length clone isolation as indicated below.

Protein Kinase cDNAs

Four different full-length PK cDNAs have been cloned from sunflower cDNA libraries. Isolation of full-length PK cDNA clones was performed with three rounds of cloning efforts using PCR-based techniques. The first step of the PK cloning was performed by PCR amplification using degenerate primers based on conserved regions between pto, fen and an Arabidopsis PK (Table 1). The initial PCR amplification resulted in the expected bands (about 350 bp). The anticipated PCR products were isolated from the gel, and then re-amplified. The PCR products were cloned into TA vectors. Restriction digestions of cloned fragments with Alu I and Msp I resulted in several different patterns. Six clones were identified as PK positive. Four of the six PK clones showed differences only at the degenerate primer regions and were considered as one group. PK positive clones were classified into three different groups of PK homologous (PK1, PK4 and PK5) based on sequence similarity. Gene-specific primers (Table 2b) were made for cloning of the 3′ and 5′ end of the three different groups of PK. Finally, PK clones containing 5′ end sequence were used to design new primers (Table 2c) for cloning full-length cDNA clones. The amino acid sequence of PK1A is highly similar to that of PK1B (FIG. 1). Both are closely related to PTO kinase from tomato (FIG. 1), which is a disease resistance protein against bacterial speck disease. Sequence comparison indicated that PK4 was highly similar to a receptor-like protein kinase and disease resistance protein kinase. Currently, for the PK5 group, only one 5′-end clone has been sequenced. It had 971 bp long and coded a 170 amino acid protein. A BLASTX search showed it had 68% identity with protein kinase APK1A from Arabidopsis.

NBS-LRR Type R Gene Homologs

The PCR products were amplified from sunflower and maize genomic DNAs and sunflower cDNA libraries using degenerate primers. One major expected band of about 500 bp was amplified from a sunflower source using NBS-LRR primers. A similar size band was amplified from maize genomic DNA. These expected bands amplified from the cDNA library mix were isolated and/or re-amplified, and then cloned into TA vectors. Separate PCR amplifications of sunflower genomic DNA and cDNAs using degenerate NBS-LRR primers each produced a large band around 500 bp. Restriction digestion of cloned fragments with Alu I and Msp I resulted in several different patterns. The presence of a heterogeneous PCR product suggested the involvement of a multigene family. At least one representative clone was selected from each different digestion group for sequence analysis. A total of six different R gene homologs from sunflower were identified using the BLAST algorithm to search GenBank. Based on the initial sequence information several gene specific primers were made (Table 1b) to clone both the 5′ and 3′ ends by PCR amplification. Four clones have been isolated. Two 3′-end clones (RS6-8 and RS7-4) and two 5′-end clones (RAS4-5 and RAS5-1) can form two contigs (RS6-8 contig and RS7-4 contig) (SEQ ID NOs: 7, 9-12, and 14). Both contigs showed high homology with the tobacco mosaic virus (TMV) resistance gene N, the downy mildew resistance gene and the rust resistance gene (FIGS. 3 and 4). In summary, six NBS-LRR type homologs were isolated using a PCR-based cloning strategy. R homolog clones from sunflower showed the highest homology to the R genes from other dicot plants

EXAMPLE 2

Transformation and Regeneration of Transgenic Maize Plants

Immature maize embryos from greenhouse donor plants are bombarded with a plasmid containing the R gene operably linked to a UBI promoter (FIG. 5) and the selectable marker gene PAT (Wohlleben et al. (1988) Gene 70:25-37), which confers resistance to the herbicide Bialaphos. Alternatively, the selectable marker gene is provided on a separate plasmid. Transformation is performed as follows. Media recipes follow below.

Preparation of Target Tissue

The ears are husked and surface sterilized in 30% Chlorox bleach plus 0.5% Micro detergent for 20 minutes, and rinsed two times with sterile water. The immature embryos are excised and placed embryo axis side down (scutellum side up), 25 embryos per plate, on 560Y medium for 4 hours and then aligned within the 2.5-cm target zone in preparation for bombardment.

Preparation of DNA

A plasmid vector comprising the R gene operably linked to a UBI promoter is made. This plasmid DNA plus plasmid DNA containing a PAT selectable marker is precipitated onto 1.1 &mgr;m (average diameter) tungsten pellets using a CaCl2 precipitation procedure as follows:

100 &mgr;l prepared tungsten particles in water

10 &mgr;l (1 &mgr;g) DNA in Tris EDTA buffer (1 &mgr;g total DNA)

100 &mgr;l 2.5 M CaCl2

10 &mgr;l 0.1 M spermidine

Each reagent is added sequentially to the tungsten particle suspension, while maintained on the multitube vortexer. The final mixture is sonicated briefly and allowed to incubate under constant vortexing for 10 minutes. After the precipitation period, the tubes are centrifuged briefly, liquid removed, washed with 500 ml 100% ethanol, and centrifuged for 30 seconds. Again the liquid is removed, and 105 &mgr;l 100% ethanol is added to the final tungsten particle pellet. For particle gun bombardment, the tungsten/DNA particles are briefly sonicated and 10 &mgr;l spotted onto the center of each macrocarrier and allowed to dry about 2 minutes before bombardment.

Particle Gun Treatment

The sample plates are bombarded at level #4 in particle gun #HE34-1 or #HE34-2. All samples receive a single shot at 650 PSI, with a total of ten aliquots taken from each tube of prepared particles/DNA.

Subsequent Treatment

Following bombardment, the embryos are kept on 560Y medium for 2 days, then transferred to 560R selection medium containing 3 mg/liter Bialaphos, and subcultured every 2 weeks. After approximately 10 weeks of selection, selection-resistant callus clones are transferred to 288J medium to initiate plant regeneration. Following somatic embryo maturation (2-4 weeks), well-developed somatic embryos are transferred to medium for germination and transferred to the lighted culture room. Approximately 7-10 days later, developing plantlets are transferred to 272V hormone-free medium in tubes for 7-10 days until plantlets are well established. Plants are then transferred to inserts in flats (equivalent to 2.5″ pot) containing potting soil and grown for 1 week in a growth chamber, subsequently grown an additional 1-2 weeks in the greenhouse, then transferred to classic 600 pots (1.6 gallon) and grown to maturity. Plants are monitored and scored for disease resistance.

Bombardment and Culture Media

Bombardment medium (560Y) comprises 4.0 g/l N6 basal salts (SIGMA C-1416), 1.0 ml/l Eriksson's Vitamin Mix (1000X SIGMA-1511), 0.5 mg/l thiamine HCl, 120.0 g/l sucrose, 1.0 mg/l 2,4-D, and 2.88 g/l L-proline (brought to volume with D-I H2O following adjustment to pH 5.8 with KOH); 2.0 g/l Gelrite (added after bringing to volume with D-I H2O); and 8.5 mg/l silver nitrate (added after sterilizing the medium and cooling to room temperature).

Plant regeneration medium (288J) comprises 4.3 g/l MS salts (GIBCO 11117-074), 5.0 ml/l MS vitamins stock solution (0.100 g nicotinic acid, 0.02 g/l thiamine HCL, 0.10 g/l pyridoxine HCL, and 0.40 g/l glycine brought to volume with polished D-I H2O) (Murashige and Skoog (1962) Physiol. Plant. 15:473), 100 mg/l myo-inositol, 0.5 mg/l zeatin, 60 g/l sucrose, and 1.0 ml/l of 0.1 mM abscisic acid (brought to volume with polished D-I H2O after adjusting to pH 5.6); 3.0 g/l Gelrite (added after bringing to volume with D-I H2O); and 1.0 mg/l indoleacetic acid and 3.0 mg/l bialaphos (added after sterilizing the medium and cooling to 60° C.).

EXAMPLE 3

Virus-mediated Transformation

The methods of the invention involve introducing a nucleotide construct into a plant. By “introducing” is intended presenting to the plant the nucleotide construct in such a manner that the construct gains access to the interior of a cell of the plant. The methods of the invention do not depend on a particular method for introducing a nucleotide construct to a plant, only that the nucleotide construct gains access to the interior of at least one cell of the plant. Methods for introducing nucleotide constructs into plants are known in the art including, but not limited to, stable transformation methods, transient transformation methods, and virus-mediated methods.

By “stable transformation” is intended that the nucleotide construct introduced into a plant integrates into the genome of the plant and is capable of being inherited by progeny thereof. By “transient transformation” is intended that a nucleotide construct introduced into a plant does not integrate into the genome of the plant.

The nucleotide constructs of the invention may be introduced into plants by contacting plants with a virus or viral nucleic acids. Generally, such methods involve incorporating a nucleotide construct of the invention within a viral DNA or RNA molecule. It is recognized that the an R protein of the invention may be initially synthesized as part of a viral polyprotein, which later may be processed by proteolysis in vivo or in vitro to produce the desired recombinant protein. Further, it is recognized that promoters of the invention also encompass promoters utilized for transcription by viral RNA polymerases. Methods for introducing nucleotide constructs into plants and expressing a protein encoded therein, involving viral DNA or RNA molecules, are known in the art. See, for example, U.S. Pat. Nos. 5,889,191, 5,889,190, 5,866,785, 5,589,367 and 5,316,931; herein incorporated by reference.

EXAMPLE 4

Agrobacterium-mediated Transformation

For Agrobacterium-mediated transformation of maize with an R gene, preferably the method of Zhao is employed (U.S. Pat. No. 5,981,840, and PCT patent publication WO98/32326; the contents of which are hereby incorporated by reference). Briefly, immature embryos are isolated from maize and the embryos contacted with a suspension of Agrobacterium, where the bacteria are capable of transferring the R gene to at least one cell of at least one of the immature embryos (step 1: the infection step). In this step the immature embryos are preferably immersed in an Agrobacterium suspension for the initiation of inoculation. The embryos are co-cultured for a time with the Agrobacterium (step 2: the co-cultivation step). Preferably the immature embryos are cultured on solid medium following the infection step. Following this co-cultivation period an optional “resting” step is contemplated. In this resting step, the embryos are incubated in the presence of at least one antibiotic known to inhibit the growth of Agrobacterium without the addition of a selective agent for plant transformants (step 3: resting step). Preferably the immature embryos are cultured on solid medium with antibiotic, but without a selecting agent, for elimination of Agrobacterium and for a resting phase for the infected cells. Next, inoculated embryos are cultured on medium containing a selective agent and growing transformed callus is recovered (step 4: the selection step). Preferably, the immature embryos are cultured on solid medium with a selective agent resulting in the selective growth of transformed cells. The callus is then regenerated into plants (step 5: the regeneration step), and preferably calli grown on selective medium are cultured on solid medium to regenerate the plants.

EXAMPLE 5

Transformation and Regeneration of Transgenic Soybean Embryos

Soybean embryos are bombarded with a plasmid containing the R gene operably linked to a UBI promoter (FIG. 5) as follows. To induce somatic embryos, cotyledons, 3-5 mm in length dissected from surface-sterilized, immature seeds of the soybean cultivar A2872, are cultured in the light or dark at 26° C. on an appropriate agar medium for six to ten weeks. Somatic embryos producing secondary embryos are then excised and placed into a suitable liquid medium. After repeated selection for clusters of somatic embryos that multiplied as early, globular-staged embryos, the suspensions are maintained as described below.

Soybean embryogenic suspension cultures can maintained in 35 ml liquid media on a rotary shaker, 150 rpm, at 26° C. with florescent lights on a 16:8 hour day/night schedule. Cultures are subcultured every two weeks by inoculating approximately 35 mg of tissue into 35 ml of liquid medium.

Soybean embryogenic suspension cultures may then be transformed by the method of particle gun bombardment (Klein et al. (1987) Nature (London) 327:70-73, U.S. Pat. No. 4,945,050). A Du Pont Biolistic PDS 1000/HE instrument (helium retrofit) can be used for these transformations.

A selectable marker gene that can be used to facilitate soybean transformation is a transgene composed of the 35S promoter from Cauliflower Mosaic Virus (Odell et al. (1985) Nature 313:810-812), the hygromycin phosphotransferase gene from plasmid pJR225 (from E. coli; Gritz et al. (1983) Gene 25:179-188), and the 3′ region of the nopaline synthase gene from the T-DNA of the Ti plasmid of Agrobacterium tumefaciens. The expression cassette comprising the R gene operably linked to the UBI promoter can be isolated as a restriction fragment. This fragment can then be inserted into a unique restriction site of the vector carrying the marker gene.

To 50 &mgr;l of a 60 mg/ml 1 &mgr;m gold particle suspension is added (in order): 5 &mgr;l DNA (1 &mgr;g/&mgr;l), 20 &mgr;l spermidine (0.1 M), and 50 &mgr;l CaCl2 (2.5 M). The particle preparation is then agitated for three minutes, spun in a microfuge for 10 seconds and the supernatant removed. The DNA-coated particles are then washed once in 400 &mgr;l 70% ethanol and resuspended in 40 &mgr;l of anhydrous ethanol. The DNA/particle suspension can be sonicated three times for one second each. Five microliters of the DNA-coated gold particles are then loaded on each macro carrier disk.

Approximately 300-400 mg of a two-week-old suspension culture is placed in an empty 60×15 mm petri dish and the residual liquid removed from the tissue with a pipette. For each transformation experiment, approximately 5-10 plates of tissue are normally bombarded. Membrane rupture pressure is set at 1100 psi, and the chamber is evacuated to a vacuum of 28 inches mercury. The tissue is placed approximately 3.5 inches away from the retaining screen and bombarded three times. Following bombardment, the tissue can be divided in half and placed back into liquid and cultured as described above.

Five to seven days post bombardment, the liquid media may be exchanged with fresh media, and eleven to twelve days post-bombardment with fresh media containing 50 mg/ml hygromycin. This selective media can be refreshed weekly. Seven to eight weeks post-bombardment, green, transformed tissue may be observed growing from untransformed, necrotic embryogenic clusters. Isolated green tissue is removed and inoculated into individual flasks to generate new, clonally propagated, transformed embryogenic suspension cultures. Each new line may be treated as an independent transformation event. These suspensions can then be subcultured and maintained as clusters of immature embryos or regenerated into whole plants by maturation and germination of individual somatic embryos.

EXAMPLE 6

Transformation and Regeneration of Sunflower Meristem Tissues

Sunflower meristem tissues are transformed with an expression cassette containing the R gene operably linked to a UBI promoter as follows (see also European Patent Number EP 0 486233, herein incorporated by reference, and Malone-Schoneberg et al. (1994) Plant Science 103:199-207). Mature sunflower seed (Helianthus annuus L.) are dehulled using a single wheat-head thresher. Seeds are surface sterilized for 30 minutes in a 20% Chlorox bleach solution with the addition of two drops of Tween 20 per 50 ml of solution. The seeds are rinsed twice with sterile distilled water.

Split embryonic axis explants are prepared by a modification of procedures described by Schrammeijer et al. (Schrammeijer et al. (1990) Plant Cell Rep. 9: 55-60). Seeds are imbibed in distilled water for 60 minutes following the surface sterilization procedure. The cotyledons of each seed are then broken off, producing a clean fracture at the plane of the embryonic axis. Following excision of the root tip, the explants are bisected longitudinally between the primordial leaves. The two halves are placed, cut surface up, on GBA medium consisting of Murashige and Skoog mineral elements (Murashige et al. (1962) Physiol. Plant., 15: 473-497), Shepard's vitamin additions (Shepard (1980) in Emergent Techniques for the Genetic Improvement of Crops (University of Minnesota Press, St. Paul, Minn.), 40 mg/l adenine sulfate, 30 g/l sucrose, 0.5 mg/l 6-benzyl-aminopurine (BAP), 0.25 mg/l indole-3-acetic acid (IAA), 0.1 mg/l gibberellic acid (GA3), pH 5.6, and 8 g/l Phytagar.

The explants are subjected to microprojectile bombardment prior to Agrobacterium treatment (Bidney et al. (1992) Plant Mol. Biol. 18: 301-313). Thirty to forty explants are placed in a circle at the center of a 60×20 mm plate for this treatment. Approximately 4.7 mg of 1.8 mm tungsten microprojectiles are resuspended in 25 ml of sterile TE buffer (10 mM Tris HCl, 1 mM EDTA, pH 8.0) and 1.5 ml aliquots are used per bombardment. Each plate is bombarded twice through a 150 mm nytex screen placed 2 cm above the samples in a PDS 1000® particle acceleration device.

Disarmed Agrobacterium tumefaciens strain EHA105 is used in all transformation experiments. A binary plasmid vector comprising the expression cassette that contains the R gene operably linked to the UBI promoter is introduced into Agrobacterium strain EHA105 via freeze-thawing as described by Holsters et al. (1978) Mol. Gen. Genet. 163:181-187. This plasmid further comprises a kanamycin selectable marker gene (i.e, nptII). Bacteria for plant transformation experiments are grown overnight (28° C. and 100 RPM continuous agitation) in liquid YEP medium (10 gm/l yeast extract, 10 gm/l Bactopeptone, and 5 gm/l NaCl, pH 7.0) with the appropriate antibiotics required for bacterial strain and binary plasmid maintenance. The suspension is used when it reaches an OD600 of about 0.4 to 0.8. The Agrobacterium cells are pelleted and resuspended at a final OD600 of 0.5 in an inoculation medium comprised of 12.5 mM MES pH 5.7, 1 gm/l NH4Cl, and 0.3 gm/l MgSO4.

Freshly bombarded explants are placed in an Agrobacterium suspension, mixed, and left undisturbed for 30 minutes. The explants are then transferred to GBA medium and co-cultivated, cut surface down, at 26° C. and 18-hour days. After three days of co-cultivation, the explants are transferred to 374B (GBA medium lacking growth regulators and a reduced sucrose level of 1%) supplemented with 250 mg/l cefotaxime and 50 mg/l kanamycin sulfate. The explants are cultured for two to five weeks on selection and then transferred to fresh 374B medium lacking kanamycin for one to two weeks of continued development. Explants with differentiating, antibiotic-resistant areas of growth that have not produced shoots suitable for excision are transferred to GBA medium containing 250 mg/l cefotaxime for a second 3-day phytohormone treatment. Leaf samples from green, kanamycin-resistant shoots are assayed for the presence of NPTII by ELISA and for the presence of transgene expression by assaying for R protein activity.

NPTII-positive shoots are grafted to Pioneer® hybrid 6440 in vitro-grown sunflower seedling rootstock. Surface sterilized seeds are germinated in 48-0 medium (half-strength Murashige and Skoog salts, 0.5% sucrose, 0.3% gelrite, pH 5.6) and grown under conditions described for explant culture. The upper portion of the seedling is removed, a 1 cm vertical slice is made in the hypocotyl, and the transformed shoot inserted into the cut. The entire area is wrapped with parafilm to secure the shoot. Grafted plants can be transferred to soil following one week of in vitro culture. Grafts in soil are maintained under high humidity conditions followed by a slow acclimatization to the greenhouse environment. Transformed sectors of T0 plants (parental generation) maturing in the greenhouse are identified by NPTII ELISA and/or by the R protein activity analysis of leaf extracts while transgenic seeds harvested from NPTII-positive T0 plants are identified by the R protein activity analysis of small portions of dry seed cotyledon.

An alternative sunflower transformation protocol allows the recovery of transgenic progeny without the use of chemical selection pressure. Seeds are dehulled and surface-sterilized for 20 minutes in a 20% Chlorox bleach solution with the addition of two to three drops of Tween 20 per 100 ml of solution, then rinsed three times with distilled water. Sterilized seeds are imbibed in the dark at 26° C. for 20 hours on filter paper moistened with water. The cotyledons and root radical are removed, and the meristem explants are cultured on 374E (GBA medium consisting of MS salts, Shepard vitamins, 40 mg/l adenine sulfate, 3% sucrose, 0.5 mg/l 6-BAP, 0.25 mg/l IAA, 0.1 mg/l GA, and 0.8% Phytagar at pH 5.6) for 24 hours under the dark. The primary leaves are removed to expose the apical meristem, around 40 explants are placed with the apical dome facing upward in a 2 cm circle in the center of 374M (GBA medium with 1.2% Phytagar), and then cultured on the medium for 24 hours in the dark.

Approximately 18.8 mg of 1.8 &mgr;m tungsten particles are resuspended in 150 &mgr;l absolute ethanol. After sonication, 8 &mgr;l of it is dropped on the center of the surface of macrocarrier. Each plate is bombarded twice with 650 psi rupture discs in the first shelf at 26 mm of Hg helium gun vacuum.

The plasmid of interest is introduced into Agrobacterium tumefaciens strain EHA105 via freeze thawing as described previously. The pellet of overnight-grown bacteria at 28 ° C. in a liquid YEP medium (10 g/l yeast extract, 10 g/l Bactopeptone, and 5 g/l NaCl, pH 7.0) in the presence of 50 &mgr;g/l kanamycin is resuspended in an inoculation medium (12.5 mM 2-mM 2-(N-morpholino) ethanesulfonic acid, MES, 1 g/l NH4Cl and 0.3 g/l MgSO4 at pH 5.7) to reach a final concentration of 4.0 at OD 600. Particle-bombarded explants are transferred to GBA medium (374E), and a droplet of bacteria suspension is placed directly onto the top of the meristem. The explants are co-cultivated on the medium for 4 days, after which the explants are transferred to 374C medium (GBA with 1% sucrose and no BAP, IAA, GA3 and supplemented with 250 &mgr;g/ml cefotaxime). The plantlets are cultured on the medium for about two weeks under 16-hour day and 26° C. incubation conditions.

Explants (around 2 cm long) from two weeks of culture in 374C medium are screened for R protein activity using assays known in the art. After positive (i.e., for R protein expression) explants are identified, those shoots that fail to exhibit R protein activity are discarded, and every positive explant is subdivided into nodal explants. One nodal explant contains at least one potential node. The nodal segments are cultured on GBA medium for three to four days to promote the formation of auxiliary buds from each node. Then they are transferred to 374C medium and allowed to develop for an additional four weeks. Developing buds are separated and cultured for an additional four weeks on 374C medium. Pooled leaf samples from each newly recovered shoot are screened again by the appropriate protein activity assay. At this time, the positive shoots recovered from a single node will generally have been enriched in the transgenic sector detected in the initial assay prior to nodal culture.

Recovered shoots positive for R protein expression are grafted to Pioneer hybrid 6440 in vitro-grown sunflower seedling rootstock. The rootstocks are prepared in the following manner. Seeds are dehulled and surface-sterilized for 20 minutes in a 20% Chlorox bleach solution with the addition of two to three drops of Tween 20 per 100 ml of solution, and are rinsed three times with distilled water. The sterilized seeds are germinated on the filter moistened with water for three days, then they are transferred into 48 medium (half-strength MS salt, 0.5% sucrose, 0.3% gelrite pH 5.0) and grown at 26° C. under the dark for three days, then incubated at 16-hour-day culture conditions. The upper portion of selected seedling is removed, a vertical slice is made in each hypocotyl, and a transformed shoot is inserted into a V-cut. The cut area is wrapped with parafilm. After one week of culture on the medium, grafted plants are transferred to soil. In the first two weeks, they are maintained under high humidity conditions to acclimatize to a greenhouse environment.
